Why do you say this? Was there something specific that you were
expecting that you didn't see?
I tried this experiment with both gcc-4.0.x and gcc-4.1.x, replacing the
--with-target option with a --target option. In both cases, I see that
code is being scheduled for an SB-1 cpu.
I verified this by compiling a small testcase with -O2 -dS
-fsched-verbose=2. This dumps some instruction scheduling info to
stderr. This output has lines like this:
;; 14--> 23 $f0=$f12*$f0 :sb1_fp1
which proves that SB-1 scheduling info is being used.
